Quizplus · Accepted Answer

Model validation is an iterative process that involves testing and evaluating the model against real-world data. While a model may be considered valid based on how well it performs according to certain criteria, it is difficult to ensure that it is 100 percent valid. Different types of testing and validation methods may be used to assess the accuracy and reliability of a model, but there is always a degree of uncertainty or margin of error involved. Therefore, it is best to use multiple tests and approaches to validate a model rather than relying on a single measure.
